With a smidge over 1200 miles on the clock, the Vishnu PROcede installed, and more seat time, I'm ready to talk about the performance of the 1series.
The engine is a peach. As you can see from the graph, power and torque are up globally. Low end torque is softer than my 335i, but the overall mapping is much nicer across the board. At wide open throttle tip in, it just pulls harder and harder to the point that getting in trouble in a hurry would not be an issue. The tires will lose traction and rip on the 1-2 upshift, and again on the 2-3.
There is some concern about the high RPM puke-n-die. I spoke with Dustin at Vishnu about this, and he said it is intentional for hot air correction. I've revved it just beyond 6500 on the street, and I have not felt it exhibit this behavior at all. Looking at the shape of the dyno graph, this power reduction would be really easy to detect.
I'm satisfied with these numbers, particularly since they were attained with only 860 miles on the car. With 200 pounds less weight, nearly 20whp more, less mods, and a superior area under the curve, this car would humiliate my poor little old X in a contest of speed.
Project update 12/22:
Intakes and corresponding mapping picked up a ton of power on the dyno.
Purple- Stock
Red- PROcede S0 Doomsday mapping
Navy- PROcede S1 nonDoomsday mapping + intakes
